What are Object Styles in InDesign
Object Styles in Adobe InDesign allow you to save and reuse formatting applied to an InDesign object. Using object styles you can quickly format a document with a consistent look and feel, and control and alter the formatting of multiple objects all from one central easy to use panel. Within the object styles panel you can reposition styles and also set default styles for specific types of object such as text frame or graphics object.
One advantage of objects styles is the ability to control the formatting of strokes, corners, text frames, story options, text wrap, frame fitting, export tagging and a wide range of effects. To work with object styles you use the object styles panel which is found under the window menu under styles. Using this panel you can create new object styles, redefine existing styles, clear overrides that have been made to styles, duplicate existing styles and even load in styles from other InDesign indd files.
When creating InDesign documents object styles can be of particular use in complying with brand guidelines, as they ensure formatting is kept consistent across multiple individual objects and avoid small difference in individual objects which can negatively affect the brand.
